Press Release

LOWELL, Mass.--(BUSINESS WIRE)-- M/A-COM Technology Solutions Holdings, Inc. (NASDAQ: MTSI) ("MACOM"), a leading supplier of high-performance analog RF, microwave, millimeterwave and photonic semiconductor products, today announced a revision to its financial results for its fiscal second quarter ended April 3, 2015, as originally reported on April 28, 2015.

In May 2015, subsequent to MACOM's April 28, 2015 fiscal second quarter 2015 earnings press release but prior to the filing of its Quarterly Report on Form 10-Q for the fiscal second quarter ended April 3, 2015, MACOM received notice that a private company in which it held a minority equity investment was sold to a third party and the proceeds MACOM would receive at closing would be less than the carrying value previously reported on MACOM's consolidated financial statements in the April 28, 2015 earnings release. As required under U.S. generally accepted accounting principles (GAAP), MACOM wrote-down the investment to the estimated the net proceeds that MACOM will receive from the sale, and recorded a charge of $3.5 million to other income (expense), resulting in an increase of its net loss per diluted share of $0.05, or $0.15 and $0.28 net loss per diluted share for the three and six months ended April 3, 2015, respectively.

This non-cash, non-operating charge did not affect MACOM's previously reported non-GAAP earnings per share of $0.41 in the fiscal second quarter of 2015. A reconciliation between revised GAAP and non-GAAP financial data is included in the supplemental financial data attached to this press release. The revised financial statements reflecting the impairment of the minority equity investment are also attached to this press release.

Non-GAAP Financial Measures

In addition to GAAP reporting, MACOM provides investors with non-GAAP financial information, including revenue, gross margin, operating margin, operating income, net income, earnings per share, EBITDA and other data calculated on a non-GAAP basis. This non-GAAP information excludes the operations of Nitronex prior to the date of acquisition, discontinued operations, the impact of fair value accounting in merger and acquisitions (M&A) of businesses, M&A costs, including acquisition and related integration costs, certain cost savings from synergies expected from M&A activities, income and expenses from transition services related to M&A activities, expected amortization of acquisition-related intangibles, share-based and other non-cash compensation expense, certain cash compensation, restructuring charges, litigation settlement and costs, changes in the carrying values of assets and liabilities measured at fair value, contingent consideration, amortization of debt discounts and issuance costs, other non-cash expenses, earn-out costs, exited leased facility costs and certain income tax items. Management does not believe that the excluded items are reflective of MACOM's underlying performance. The exclusion of these and other similar items from MACOM's non-GAAP presentation should not be interpreted as implying that these items are non-recurring, infrequent or unusual. These and other similar items are also excluded from EBITDA, which is non-GAAP earnings before interest, income taxes, depreciation and amortization. MACOM believes this non-GAAP financial information provides additional insight into MACOM's on-going performance and has, therefore, chosen to provide this information to investors for a consistent basis of comparison and to help them evaluate the results of MACOM's on-going operations and enable more meaningful period to period comparisons. These non-GAAP measures are provided in addition to, and not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial data attached to this press release.
